The upgrade of the back-end node is taking longer than expected. Most of the routes are working as usual, as some routes (Kava, zkSync, Polygon zkEVM) are suspended temporarily for now. All the affected transactions will arrive once the upgrade is complete.

We are sincerely sorry for the inconvenience.
Thank you for your support !
